This patch allows to set an eventfd for fsl-mc device interrupts and also to trigger the interrupt eventfd from userspace for testing. All fsl-mc device interrupts are MSIs. The MSIs are allocated from the MSI domain only once per DPRC and used by all the DPAA2 objects. The interrupts are managed by the DPRC in a pool of interrupts. Each device requests interrupts from this pool. The pool is allocated when the first virtual device is setting the interrupts. The pool of interrupts is protected by a lock. The DPRC has an interrupt of its own which indicates if the DPRC contents have changed. However, currently, the contents of a DPRC assigned to the guest cannot be changed at runtime, so this interrupt is not configured.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
